PyQt5 Alternative to setHandlesChildEvents

I have been porting a PyQt4 application to use PyQt5. Everything seems to work fine apart from one thing: setHandlesChildEvents is now obsolete with QGraphicsItemGroup meaning I can no longer pick up on click events on my items within a group.

What is the alternative approach with PyQt5? I have tried replacing it with self.MyGroup.setFiltersChildEvents(False) but this has no effect.
